DEVICE FOR CONTROLLING BOTH THE IGNITION CIRCUIT AND THE SUPPLY OF GAS TO THE CABBURETQR.

I A pnomon'mea Kay 5, 1925. Serial Ito/28,277. Q

The object of my invention is to provide a novel device for locking the ignition switch of an automobile engine to revent unauthorized use of the car. The evice includes a dial and a valve operated from the dial.

I attain these and other objects of my inven-- tion by the device illustrated in the accompanying drawings, in which p Figure 1' is a vertical section, partly in side elevation, of my device applied to an automobile Fig. 2 is a front plan view of the dial element; 7

Fig. 3 is a section on line 3--3 of Fig. 2; Fig. 4 is a detail horizontal section on line 4 -4 of Fig. 1;

Fig. .5 is a valve23;

Fig. 6 is a transverse section on line 6-6 of F1g. 5, I

Fi 7 1s a transverse section on line 77 of Fig. 5; and k Fig. 8 is a transverse section on line 88 of Fig. 5.

Like characters of reference designate like parts in each of the several views.

Referring to the accompanym drawings, D designates the dash board 0 the car in which is mounted a cylindrical casin 30 carrying the dial 27 in front of whic is mounted the crystal 29. I provide a shaft vertical section through 1 having a knob affixed on its outer end and a bevel gear 16 at the other end. I provide a hand 3 affixed to the shaft 1 and another and shorter hand 6 mounted on collar 5 which collar also carries the gear 4 said gear 4 meshing with the pinion 7 aflixed to gear 8 which in turn meshes with the pinion 9 on shaft 1, these gears functioning to effect a.

ratio of 12 to 1 between the long hand 3 and the short hand 6 so that the lar e hand will go around the dial 12 times while the small hand is going around once. Also mounted on shaft 1 I provide a screw threaded enlargement 10 operatively engaging the internally threaded sleeve 11, which sleeve has a projecting arm 12 slidably engagmg 1n the groove 13, as shown in Fig. 1. Aflixed to sleeve 11 are spring contact arms 14 which may be operated into and out of conjtFact with the contact points 15, as shown 1n Meshing with gear 16 on shaft 1, I provide a similar bevel gear 17 on the vertical shaft 18, which shaft-is provlded with a biof knobs2l'on the end 22 of valve 23. Valve 23 includes the stem 22, a sleeve 32 rotatably mounted in a second sleeve 26 which sleeve is rotatably mounted in socket 25 of the stationary sleeve 24. Sleeve 26 is provided with an aperture 31 positioned to register with the passage 41 in stationary sleeve 24 which communlcates with pipe 42. Sleeve 32 is provided with an aperture 33 positioned to register with aperture 31 and passage 41. Valve stem 22 is provided with an aperture 37, positioned to register with apertures 33 and 31 and passage 41 to pipe 42. Aperture 37 opens out of the central channel 36 in stem 22. The lower end of valve stem 22 is threaded externally as at 34 and has a threaded engagement with the internall threaded channel 35 of stationary sleeve 2 I provide a hollow screw 38 seated in the internally threaded lower end 40 of valve'stem 22, as shown in Fig. 5, a suitable washer 39 being interposed between screw 38 and the lower end of the valve stem. I also provide a coupling or union 44 engaging in the lower end of stationary valve stem 24 on the lower end of which cap-46 engages. I provide a similar cap 43 engaging on the threaded stem in which the end of pipe 42 is mounted. Mounted on the upper end of stationa sleeve 24, I provide stationary ring 47 whic has'a dial affixed to that sleeve.- Sleeve 47 has the graduations 48 marked thereon.

which is provided with the graduations 50,

as shown in Fig. 1; Ring 49 is provided at its base withthe knurled annular flan 51. On the underside of ring 49 I provi e an annular groove 52 having a series of stop recesses or sockets 53, as shown in Fi 5, adapted to be engaged by the pin 54 WhlCh is pressed upward by the s ring 55, members 54 and 55 being mounte in the socket 56 provided in ring 47 and sleeve 24, as shown 1n Fig. 5. I provide a pin-57 aflixed in the upper end of sleeve 26 and extending into a slot 58 of ring 51, whereby the 'ring 51 and sleeve 26will rotate together. I provide a knurled head 59 attached to inner sleeve 32 by the screws 60. In operatin the invention, the knob 2 is rotated until t e hands are .at predetermined figures, as, for example, the short hand at 10 and the long hand at 12, the hands operating in the same manner as the hands of a clock.

In this predetermined position the aperture 37 of valve stem 22 will be alined with the passage 41 in stationary valve stem 24. The

nurled flange 59, which has a suitable index point orline, is set at the predetermined fi e on the graduation 50 of ring 49, in w ich position the aperture 33 of sleeve 42 will be alined with the aperture 37 of valve stem 22 and with the passage 41 of stationary valvestem 24. Knurled flange 51, which also bears a suitable index point or line, is rotated until that index point is set at a predetermined figure of the raduation 48 of ring 47. The rotation of t e knurled flange 51 and its integral ring 49 causes the rotation also of sleeve 26 by reason of the engagement of pin 57 carried'by sleeve 26 in the slot 58 of ring 49, as shown in Figs. 5 and 7. Sleeve 26 has the aperture 31 which is brought into alinement with the apertures 37 of valve stem 22, aperture 33 of sleeve 32 and passage 41 of sleeve 32 and assage 41 of valve stem 24, as shown in igs. 5 and 6, thus permitting flow of fuel to the carburetor through pipe 42. The bottom half 52 of ring 49 is provided with spaced recesses 53 with which thepin 54, urged by spring 56, contacts to. prevent the rin 49 being accidentally shifted.

is my purpose to provide each indiyidual device with the hand of dial 29 adjusted toa different combination, no two like combinations being put on the market.

It is also within the contemplation of my invention to provide suitable means for permitting the owner to gain access to the hands to set them to a different combination.

The device controls both the supply of gas to the carburetor and at the same time governs the ignition circuit.

In Fig. 1 of the drawings the device is illustrated set to operate the car, with the valve passages in communication and with the ignition switch closed by the contact of spring arms 14 with the contact points 15. When the knob 2 is rotated it rotates shaft 1 and this actuates sleeve 11 and spring arms 14 carried by that sleeve, thus breaking the electrical circuit between members 14 andl5 and simultaneously actuates the valve stem 22 to cut off the supply of gas to the carburetor.

What I claim is:-

1. In a. device of the class described, an operating device, a valve stem with which said device is operatively connected,.said

valve stem having a central channel and a lateral aperture opening out of said channel, a sleeve rotatively mounted over the valve stem, said sleeve having an aperture positioned in the same plane as the lateral aperture of the rotatable valve stem, said sleeve having a knurled flange for manually rotating same and the flange having an index marking, a ring positioned under the knurled flan e and having graduation markings, the said ring also'having a knurled flange integral therewith, a sleeve operative 1 connected with and rotated by the rotation of said ring, the aforesaid sleeve having an aperture in the same plane as the aperture in thefirst mentioned sleeve and in the valve stem, a stationary sleeve having a lateral passage lying in the same plane as the apertures in the aforesaid sleeve and valve stem, said passage being in communication with a pipe leading to the carburetor from the fuel tank, and a ring bearing gradnation markings, said ring being aflixed on the upper end of the stationary valve stem and under the knurled flange of the rotatable ring, and a pipe leading to the carburetor.
